Questions tagged [pip]

Use for questions about the Python package installer but not about Picture-in-Picture

pip is the package installer for Python. You can use pip to install packages from the Python Package Index and other indexes. The name is a recursive acronym for "Pip Installs Packages".

It replaces easy_install and is an improved Python package installer. The differences between easy_install and pip can be found in a discussion on the Python Packaging User Guide.

Please do not use the tag for Picture-in-Picture, use instead.
